eth0: Setting Rx mode to 0 addresses.

Hi,

I have a very old crappy computer next to me. It was running
RedHat 6.2 with no problem. So I decided to upgrade it to RH9.

During the installation process, the network card was not
recognized. I had to open up the box, check to see who was
the manufacturer, then 'insmod 3c509'. Only then was the
network card recognized. But now, I'm having the following error:

eth0: Setting 3c5x9/3c5x9B half-duplex mode if_port: 0, sw_info: 0921
eth0: Setting Rx mode to 1 addresses.
eth0: Setting Rx mode to 0 addresses.

eth0: Setting 3c5x9/3c5x9B half-duplex mode if_port: 0, sw_info: 0921
eth0: Setting Rx mode to 1 addresses.
eth0: Setting Rx mode to 0 addresses.

& when it sets to 0 addresses, I lose the connection. Only when I 
hit a key on the keyboard, then it "Setting 3c5x9....", then setting
to 1 addr, then the network connection comes back up. Guessing some
kind of handshaking problem?

There's a switch that this machine is connected to. It's configured
on 'auto' as far as half/full duplex's go. But, this machine is first
connected to a Netgear 10BaseT Ethernet Hub. Then from there it goes
to the switch. At the time of 'insmod', if not specified, isn't the
default duplex on 'auto'?

My Ethernet card is a 3c509B. Could it be that the 'insmod 3c509' doesn't
understand the version 'B' of it? 

It's the first time I'm seeing this. If there was no connection at all,
then I'd understand. But connection comes up and goes...that throws me
off.

Anyone seen this? How can it be fixed? 
ThanX.


As Always,
